Chapter 15 of the Inland Boatowner's Book (available through this website) has information about the size and use of anchors on inland craft. It also has recommendations for the type and length of the line used to attach the anchor to the boat.

Just a word of warning- which is in Chapter 15- is to make sure that the first part of the line is chain (preferably about 15 to 20ft minimum) with the rest of the line polyester or nylon (8-lay Octoplait is very easy to splice into the chain). Do NOT use polypropylene as it floats and is counter productive.
Also, ensure that the line is permanently attached to the boat- so if you have to anchor, you don't throw the lot overboard without tying it on (it does happen!). Also, flake down the anchor line in a figure-of-eight shape, so that it can run out without snagging.
The longer the anchor line, the better- it needs to be at least 5 times the anticipated depth- better if 7 times. This may mean 100ft plus- my anchor is a 20kg Danforth pattern, with 5m 5/8th chain and 30m octoplait nylon line, spliced into the chain. This is suitable for a 60ft boat, and has anchored me successfully several times in tidal waters (when awaiting change of tide). it is hard to manhandle, but does work effectively!#
More info in the Inland Boat Owners Book.
Also worth getting the Port of London Authority (PLA) advice on cruising the Thames in leisure craft, as well as the byelaws, etc. They will send you a good laminated map of the tidal river, from Teddington to Sea Reach No.1 Bouy (the start of the sea proper!) www.pla.co.uk
